Can't hook functions

[NotBlue-Dev]

Hi, i get this error when i try to hook any function of NMS : System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Here is the code used for hooking :

public void InitHook(IModLogger _logger, IReloadedHooks _hooks)
        {
            logger = _logger;

            string pattern = "48 8B C4 48 89 58 08 48 89 68 10 48 89 70 18 57 41 56 41 57 48 81 EC ? ? ? ? 0F 29 70 D8 48 8D";

            Function = _hooks.CreateFunction<HookDelegate>(new Signature(pattern).Scan());
            _hooks.CreateHook(Function, new Signature(pattern).Scan());
            logger.WriteLine($"Function: {Function}");
            Hook = Function.Hook(CodeToExecute).Activate();
        }

Have you checked whether the signature scan returns a valid address? Maybe a game update has changed the relevant code.
